GridView control typical data-bound controls, such controls and data source control to be used in conjunction with the corresponding data to display, in which today's data source controls are sqlDataSourse.
Binding data-bound controls and data source control steps of:
1, first establish a connection to a database, the database in any of a drag to the interface table, the aim is to connect a string configuration database.
Table 2, will want to show data objects (database) to drag interface, this time in the interface, VS automatically creates is divided into two GridView controls and SqlDataSourse.
3, the source of the configuration data of the data source control, smart prompt button click, select the configuration Source: connecting the selected character string database (corresponding to the configuration file), to enter the next table, and then select the fields to be displayed, click to complete in the upper right corner of the GridView smart prompt, select the data source, select the default data source name to just configured.
